Automatic Water changes. It doesnt get any better then this.

Is this motor bad?

(Excuse the shaking, I was holding the camera at a weird angle)

 

[Sacohen]

Not necessarily.

I had the same problems until in found the right power supply.

This is what I have. 12 VDC 3 AMP POWER SUPPLY | AllElectronics.com

I'm going to test out one of my spare motor assemblies.

 

[KoleTang]

I think you're right. It doesn't work with the other motor either.

Note the light on the PSU.



What PSU are you using?

 

[Sacohen]

This is the power supply that I found that worked for me.
It's a 12v 2A made by Jentec technologies.

I know you are using 12v 3A and you would think that would work, but I've tried 12 v 4amp and 24v 3amp that didn't work.
I think some PSU's have circuitry that will give the pump a little more of a kick when it starts up to get it going and then it will back things down.

That's the one issue I've seen with the MasterFlex pump is the the PSU is hit and miss.

I found a Jantec on eBay. Do you know what type of connector it uses?



How does the Jantec compare to the PSU ReeferEric is using? https://www.youtube.com/watch?v=k7YWO-_TSZ8&feature=youtu.be

 

[Sacohen]

That looks like the connection that was on it.

I cut it off and am going to solder the wires to the motor.

I'm not sure how it compares to his, I never saw his PSU.

Is it just standard Live/Neutral/Ground inside the wire? Where do you attach the ground since the motor only has live and neutral? (Sorry, even though I enjoy messing with electronics, I am a bit noobish)

His PSU is in the link.

 

[Sacohen]

I didn't connect the ground.

As far as Eric's PSU all I know about it is it's a wall wart. If I remember it is 12v, I can't remember the amps though.

I finally ran all the lines and set up my profilux for the system... and then realized I need a check valve because my waste salt water is connected with a T to my waste water from the RO and I don't want salt water invading the RO system. So... one more day to wait.

Here is my Profilux setup.

S2 is the Stenner pump set up on a timer, S3 is a solenoid that feeds my ATO/RO.

It was a wall wart, 5VDC @1.2a. I haven't played with it in a while.

I did run the lines for the Stenner tonight and it's working from what I see but that was the pulling from the tank to drain. Didn't run the new mixed saltwater yet because my silo is on the other side. I'm going to try and move it this weekend but there is still 50g of water left in it. Doubt I have enough buckets for that. LOL

I'm looking for an additional masterflex 7024-20 head. Someone PM me if they have one or have a link to a cheap one.

 

[rhcpnut1]

Can any one hit me with links. I wanna try this one a budget if i can.

There's tons of information and where to find them in the thread, the info is given already. We've gone through the trouble shooting as well.

 

[rhcpnut1]

My thought eric instead of trying collect tidbits from multiple sources and probably getting something wrong i would just ask, but ill give 8 pages another shot

 

[Sacohen]

Eric can be a jerk sometimes ,

There are quite a few on Ebay.
Some are the easy load heads.

its all good sacohen id be blunt to if some jackwagon like myself hopped in this wiithout contributing, sorry being lazy. Great idea, props to this thread and glad to see it work. Have been looking for the associated but wanna get it right off the bat without waisting precious monetaries right now.

 

[rhcpnut1]

See and looking at the list, the quick load head is conflicting id seen earlier someone used a 7024-20 whats the difference between that and the 21-20. Is it just the ml pm? are they interchangable between motors and psu and such. :banghead:

 

[AquamanE]

Ian- Very Nice program features on that Profilux controller.

If i understand it correctly you are doing 6 15 minute water changes. I think Dr. Thompson is doing 4 per day. Just curious why you guys are going this route versus just once per day.

I never knew this was a thing! I'm so jealous!!
